On the other hand, when finished programs are released to many users, there are cases where programs should not be analyzed easily, in order to protect the intellectual properties or to insure system security. In such cases, we believe that it is effective to write programs that are easy to analyze at first, and transform it so that it becomes difficult to analyze. Such an equivalent transformation is called \"program scrambling.\" We present two methods for automatically scrambling programs that contain loops, and report on an experiment for validation of the methods.
